Coronary arteries largely arise from cells of the endocardium

During embryonic development, the all-important coronary arteries arise from cells previously considered incapable of producing them, according to scientists at Albert Einstein College of Medicine of Yeshiva University.

Electrophysiology: an interview with Dr Kaylene Young

Bioelectricity is an essential part of our make-up. All cells in our body communicate by electrical activity. If an electrical charge is applied to one of our muscles it will interpret that electrical activity as a signal telling it to contract.

Researchers discover new cause of hydrocephalus

Researchers at the University of Iowa have discovered a new cause of hydrocephalus, a devastating neurological disorder that affects between one and three of every 1,000 babies born. Working in mice, the researchers identified a cell signaling defect, which disrupts immature brain cells involved in normal brain development.

Smoking affects development of peripheral allergy-relevant stem cells in the blood

Environmental contaminants, such as smoking, are harmful to the human organism in relation to the occurrence of allergies. This is known. Until now, researchers had never investigated whether and to what extent environmental contaminants also affect allergy-relevant stem cells.

Medulloblastomas that arise from different cell types might require personalized treatments

Cancers arise when a normal cell acquires a mutation in a gene that regulates cellular growth or survival. But the particular cell this mutation happens in-the cell of origin-can have an enormous impact on the behavior of the tumor, and on the strategies used to treat it.

Cancer metastasis research facilitated by nanoparticle characterization technology from NanoSight

NanoSight, leading manufacturers of unique nanoparticle characterization technology, reports on the breakthrough cancer metastasis research of Dr. Hector Peinado Selgas and Dr. David Lyden's research team from Weill Cornell Medical College.

Scientists show how sorafenib can be dangerous to the heart

Scientists for the first time have evidence showing how a widely used type of "targeted" cancer drug can be dangerous to the heart.

Researchers unlock complex cellular mechanics that instruct glial progenitor cells to divide

In a new study appearing this month in the Journal of Neuroscience, researchers have unlocked the complex cellular mechanics that instruct specific brain cells to continue to divide. This discovery overcomes a significant technical hurdle to potential human stem cell therapies; ensuring that an abundant supply of cells is available to study and ultimately treat people with diseases.

mTor molecule plays a significant role in myeloid differentiation

University of Illinois cell and developmental Biology professor Fei Wang and colleagues have created a new technique to study how myeloids, a type of blood stem cell, become the white blood cells important for immune system defense against infections and tissue damage.

VEGF produced by NPCs plays a strong role in influencing microglial behavior

The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding adds a new dimension to our understanding of how resident stem cells and stem cell transplants may improve brain function.

Preclinical study finds how fat tissue fuels cancer growth

Fat progenitor cells may contribute to cancer growth by fortifying the vessels that provide needed blood to tumors, according to preclinical research findings by investigators at The University of Texas Health Science Center at Houston (UTHealth).

Bidirectional communication between breast cancer cells and nearby MSCs cause metastasis

In recent years investigators have discovered that breast tumors are influenced by more than just the cancer cells within them. A variety of noncancerous cells, which in many cases constitute the majority of the tumor mass, form what is known as the "tumor microenvironment."

NCI awards Cellerant SBIR contract to develop Megakaryocyte Progenitor Cell therapy for thrombocytopenia

Cellerant Therapeutics Inc., a biotechnology company developing novel hematopoietic stem cell-based cellular and antibody therapies for blood disorders and cancer, announced today that it has been awarded a Small Business Innovation Research (SBIR) Phase 1 contract and a Phase 2 option from the National Cancer Institute (NCI) valued up to $1,683,503.

DPP-inhibitors reduce cardiovascular events in diabetes patients

Type 2 diabetes patients who are treated with dipeptidyl peptidase-4 inhibitors have a significantly reduced risk for cardiovascular events, particularly myocardial infarction, compared with their peers who take placebo or other drugs, results of a meta-analysis show.

Study finds new regulator for heart formation

A new regulator for heart formation has been discovered by studying how embryonic stem cells adjust the packaging of their DNA. This approach to finding genetic regulators, the scientists say, may have the power to provide insight into the development of any tissue in the body - liver, brain, blood and so on.

Adult stem cells can prevent Alzheimer's disease

In the first study of its kind, researchers at Korea's leading university and the RNL Bio Stem Cell Technology Institute announced this week the results of a study that suggests an astounding possibility: adult stem cells may not only have a positive effect on those suffering from Alzheimer's disease, they can prevent the disease.

Flow cytometry isolates stem cells from brain tumors

A new video protocol in Journal of Visualized Experiments (JoVE) details an assay to identify brain tumor initiating stem cells from primary brain tumors. Through flow cytometry, scientists separate stem cells from the rest of the tumor, allowing quick and efficient analysis of target cells. This approach has been effectively used to identify similar stem cells in leukemia patients.

Researchers solve mystery of radial glial cells

Researchers at Cold Spring Harbor Laboratory (CSHL) have solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving birth to neurons that will populate the emerging cerebral cortex, the seat of cognition and executive function in the mature brain.

Scientists discover bone abnormalities in rats undergoing chronic lack of sleep

Scientists at the Medical College of Wisconsin, in a team led by Carol Everson, Ph.D., professor of neurology, cell biology, neurobiology and anatomy, have discovered abnormalities in bone and bone marrow in rats undergoing chronic lack of sleep. They discovered abnormalities in serum markers of bone metabolism in sleep-deprived rats, which led them to conduct direct measurements of bone parameters; this time in rats experiencing recurrent sleep restriction during a large portion of their young adulthood.

Biologists elucidate how muscle stem cells colonize special niches

Muscles have a pool of stem cells which provides a source for muscle growth and for regeneration of injured muscles. The stem cells must reside in special niches of the muscle for efficient growth and repair.
